A qualitative study of young drivers and deterrence based road policing

Deterrence theory is the predominant theory used to underpin road policing initiatives. However, survey research indicates that this approach may not be as effective for young drivers. This study uses focus groups, conducted in both metropolitan and regional locations in two Australian states (Queensland and Victoria), to explore three components of classical deterrence theory: certainty, severity & swiftness. The results suggest that geographical context affected perceptions of certainty with individuals from regional locations less likely to indicate that they would be caught by police for committing a traffic offence. Additionally, the use of cameras to detect road offences increased perceptions of certainty for young drivers. The results of this study suggest that police agencies should focus on undertaking actions to increase the perceptions of certainty swiftness and severity of punishment, particularly in regional areas, for young drivers who engage in illegal behaviour on the road. Where appropriate, these actions should take into account the geographical context. There may also be value in considering augmenting deterrence theory with other theoretical perspectives for this group.     

趣味性听觉材料对驾驶疲劳的作用：来自EEG的证据

疲劳驾驶是诱发交通事故的重要因素,研究驾驶疲劳的有效干预方法具有重要意义。本研究通过让驾驶员在驾驶模拟器中完成1小时的单调驾驶任务来诱发驾驶疲劳,同时记录驾驶员主观疲劳、驾驶绩效和脑电θ波功率,来探究趣味听觉材料是否可以缓解驾驶疲劳。结果发现,在单调驾驶条件下收听趣味听觉材料的驾驶员脑电θ波功率高于控制组,表明收听趣味听觉材料不利于缓解驾驶疲劳。     

An analysis of a contingency program on designated drivers at a college bar

The present study evaluated the effects of prompts and incentives on designated drivers in a bar. We defined the dependent variable as the percentage of customers either functioning as or riding with a designated driver. We used an ABCA design to evaluate the effectiveness of prompts and incentives on the dependent variable. Results indicated that the intervention was successful at increasing the ratio of safe to unsafe passengers in a bar.     

Risky driving among young male drivers: The effects of mood and passengers

Young male drivers are at greater risk of automobile crashes than other drivers. Efforts to reduce risky driving in this population have met with mixed success. The present research was designed to examine the effects of induced mood and the presence or absence of passengers on risky driving in young male drivers. Male drivers (n = 204) aged 16–18 were tested in a driving simulator. This study employed a 2 (happy/sad mood) by 2 (passenger present/absent) between-subjects factorial design, and examined driving behavior in a simulator. Measures of risky driving were combined into two factors representing speed (e.g., exceeding the speed limit) and carelessness (e.g., crossing the center line). Findings indicated that driving with a passenger resulted in faster driving than driving alone. Although there was no significant main effect of induced mood on driving, results revealed a significant interaction of mood and passenger conditions: when in a happy mood, driving with a passenger significantly increased driving speed. There were no significant effects of passenger or mood on careless driving. In conclusion, both mood and passenger presence are important factors in fast driving among young male drivers. Results are discussed in the context of developing more effective countermeasures for this at-risk population.     

The prevalence of in-vehicle driving distractions in road traffic collisions as a function of road type

While some previous research suggests that conversing with passengers is the most prevalent in-vehicle distraction while driving, others have concluded instead that it is mobile phone use. One possible explanation for these differences is that distraction prevalence varies with road type. To test this proposal the current study investigated the prevalence of in-vehicle driving distraction in road traffic collisions (RTCs) as recorded in national records from the US and New Zealand. Analysis using odds ratios suggested conversing with passengers to be a more prevalent distraction in RTCs on minor roads than on major roads, and mobile phone use to be a more prevalent distraction on major roads than on minor roads. These results show the importance of considering the type of road when investigating the prevalence of driving distractions in RTCs in future research.     

Self-regulation and tailgating behaviours among young drivers

Young drivers aged 17 to 25 years are overrepresented in road crash fatalities globally. In Queensland, Australia, tailgating is an illegal behaviour that has been attributed to at least 8,000 rear-end crashes per year. Notably, it has been found that young drivers tailgate more frequently than older drivers. This study utilised self-determination theory to understand self-regulation behind tailgating among young drivers. This theory has yet to be applied to understand tailgating but has been successful in understanding other risky driving behaviours, suggesting self-determination theory may have predictive utility in explaining tailgating. Participants (n = 609) aged 17 to 25 years (M_age = 20.61 years) completed an anonymous online survey measuring engagement in tailgating, external and internal regulation, trait self-regulation, and aggressive driving. Results indicated that young drivers less influenced by legal and non-legal sanctions are likely to engage in tailgating more frequently (lower external regulation). Young drivers influenced by safe driving values were less likely to engage in tailgating (greater internal regulation). Poorer trait self-regulation and higher measures of aggressive driving were predictors of more frequent tailgating in young drivers. The results support the development of informative campaigns centred on the self-determination theory with the aim of educating young drivers on the implications of tailgating and safe following distances.     

Refreshing Older Adults’ Driving Skills (ROADSkills): A randomized controlled trial examining the effect of video feedback

ObjectivesThis study evaluated the effectiveness of a personalized video-based driver training program on the behind-the-wheel skills of community-dwelling older adults.MethodIn this randomized controlled trial (RCT), 80 older drivers [mean age (SD) = 71.0 (3.9)] were randomly assigned to view one of two educational videos: 1) personalized video feedback on their driving (n = 40) or 2) a generic video on aging-in-place (n = 40). The primary outcome, the total number of errors accrued in a 30-minute standardized on-road evaluation, was analyzed at baseline and 4 weeks after watching the assigned video. On-road evaluations were video-recorded and scored by a blinded rater. Self-report measures of driving abilities, behaviors, and comfort were also compared.ResultsAt the 4-week follow-up, the mean difference in the number of on-road performance errors [mean (95% CI) = -12.0 (-16.6, −7.4), p < 0.001] favored the intervention group compared to controls, with significant improvements across multiple domains: vehicle control [mean (95% CI) = -4.8 (-8.1, −1.5), p < 0.01], observing the roadway [mean (95% CI) = -5.5 (-8.4, −2.6), p < 0.001], and compliance with traffic rules [mean (95% CI) = -1.3 (-2.3, −0.2), p < 0.05]. Within-group change on behind-the-wheel errors was significant for the intervention group [mean (95% CI) = -10.3 (-13.5, −7.1), p < 0.001], but not for the control group [mean (95% CI) = 1.7 (-1.6, 4.9), p > 0.05]. No significant differences were found on the self-report measures.DiscussionA novel, video-based approach that provided personalized feedback to older drivers significantly reduced behind-the-wheel errors 4-weeks post-intervention. Changes in self-reported driving behaviors and abilities were not significant. Future research will examine the long-term effects of this approach on older adults’ actual and perceived driving abilities.     

Mobile phone use while driving in Finland

Mobile phones represent one of the most common distractions for drivers and phone use while driving is particularly problematic in Finland. The aim of this research was to explore the Finnish sample of responses from ESRA2 (E-Survey of Road users' Attitudes) with a specific focus on the distracting behaviours related to mobile phone usage while driving. ESRA2 data is derived from online surveys amongst a representative sample of the adult populations in each participating country. In total a sample of 994 responses were collected in Finland for ESRA2, which included 703 responses from participants who held a driver’s licence and reported driving a car in the 30 days prior to the survey.The results provide evidence of the problematic usage of mobile phones while driving in Finland. Mobile phone use was considered across three specific types of usage: (1) handheld phone calls while driving; (2) handsfree phone calls while driving; (3) texting, emailing or social media use while driving. Almost half (49.4 %) of the sample reported using a handheld mobile phone to make a call while driving at least once in the 30 days prior to the survey. A similar percentage (41.4 %) of the sample had used a phone hands-free and 35.6 % had texted, emailed, or used social media.The study highlights how mobile phone usage is a complex and multifaceted issue and that there are a broad range of underlying factors that influence mobile phone usage depending on the way in which people engage with their mobile phone while driving. The findings suggest that a systematic approach to reducing mobile phone distraction is needed that addresses the issue through a combination of legislation, enforcement, and education.     

Does it deliver what it promises? Evaluation of cognitive distraction caused by speech-based interfaces with detection response and box task

Speech is considered a promising modality for human-machine interaction while driving, especially in reducing visual and manual distraction. However, speech-based user interfaces themselves have shown to increase cognitive distraction. There remains a lack of standardized and unambiguous methods for measuring the impact of speech-based assistants on cognitive distraction while driving. This work aims to investigate whether the combination of the box task and the detection response task (DRT) is a suitable method for assessing the cognitive distraction caused by speech-based assistants. For this purpose, participants (N = 39) engaged in artificial (n-back tasks) and natural speech-based secondary tasks (interaction with Android’s Google Assistant and Apple's Siri) differing in predefined levels of cognitive workload while performing the box task and the DRT. The results showed that DRT performance differed between the 0-back and 1-back task but not between the different cognitive workload levels of the speech-based assistants. No clear effects emerged for the box task parameters. Thus, the combination of the box task and DRT is well-suited for measuring cognitive distraction caused by artificial secondary tasks but not by natural interactions with speech-based assistants.     

Decreasing Child Distress During Needle Sticks and Maintaining Treatment Gains Over Time

This study examined the effectiveness of an intervention for reducing behavioral distress in children during needle sticks. Participants were eight children and their parents. The children received injections or venipunctures for hematological or oncological disease. The distress management intervention included instruction for children to engage in a distraction activity during needle sticks and parent training in coaching their children. The intervention was adapted to clinic and home treatment settings. Results indicated that five children exhibited significantly less distress after treatment when compared with baseline sessions, that treatment gains were maintained at follow-up for three of them, and that child distress was significantly and negatively related to use of the experimental distractor. Implications for clinical practice are discussed.
